GEORGE P. OREHORE, OF KANSAS CITY, MISSOURI.

CABLE-RAILWAY CARRYING-PULLEY.

SPECIFICATION forming part of Letters Patent No. 391,454, dated October 28 1888.

Application filed February 6, 1888. Serial No. 263,190.

To all whom it may concern:

Be it known that 1, GEORGE P. CREHORE, a citizen of the United States, residing at Kansas City, in the county of Jackson and State of Missouri, have invented a new and useful In'iprovement in Cable-Railway Carrying Pulleys, of which the following is a specification.

As at present constructed and arranged cable-railway carrying-pulleys often cease revolving through friction at the journals, and accumulations of dirt, snow, water, and other debris in the conduit, which freeze to the pulley during thehours of inactivity of the cable. \Vhen the pulleys are stuck, the power moving the cable must be largely increased, while at'the same time the cable wears ruinous flat spots in the pulleys.

It is the object of my invention to overcome these difficulties by means of anti-friction bearings and a water-tight casing about the pulley, substantially in the manner fully set forth in the following specification and accompanying drawings, forming a part of the same, in which- Figure l is a vertical section through the line ay of Fig. 3; Fig. 2, a side elevatiou,and Fig. 3 a plan.

Similar letters refer to similarparts throughout the several views.

A is the lower part of the casing made watertight, having a flange, B, to connect with the flange O of the upper part, D; ears E, to attach to any desired foundation, and two anti-friction roller-boxes, F F, connected at a a with the bottom of the oil-wells b b. The anti-friction rollers e c e e are adjusted in the boxes and to the shaft G of the pulley H in the usual way, the shaft having shoulders at c c to prevent lateral motion.

The flange 0 of the upper part, D, conforms to the flange B of the lower part of casing,and is made fast thereto by any necessary number of bolts, asf.

In the construction of the upper part, I), while not confining myself to any particular line of contour,I use the shape herein described as being convenient for the present purpose, my object being to inelose as much of the pulley H as the cable I will permit, leaving only (No model.)

a minimum working-space between the pulley and easing. I therefore, at a proper distance below the cable, curve the casing down as close as may be to the bottom of the groovein pulley H, as shown at h,and follow the groove to its upper edge, crossing it at i and continuing to the curved upperedge ofeasin'g at j. The curve from h to lo, Fig. 3, is the opposite of. but in other respects like, the curve from h to j. The surface cut by the curved line k h i gradually flattens out and merges into the end surface, I, at or near the line m. The curved surface a 0 p r is similar to that just described. Lugs J J hold the journals of the shaft G to their antifriction bearings. The oilwells bb are supplied through the apertures K K. Spirit-levels L M protected by covers 0 N are permanently attached as a ready means of adjusting the pulleys to a vertical position at all times. R and S are holes made use of in lifting the casing out of the conduit with hooks.

The anti-friction bearings may be set aside and ordinary journal-bearings substituted in lieu of them whenever it is deemed expedient, without lessening the necessity for the casing, and in such a case the contour of the casing may be modified to suit the changed condition of the inclosed bearings. Neither do I confine my invention to any one kind of antifriction bearing.

Having fully described my invention, what I desire to claim and secure by Letters Patent 1. A cover or casing adapted to protect a pulley of a cable railway by entirely inclosiug the same except where the cable runs upon said pulley, substantially as shown and described. I

2. The combination, with a cable-railway pulley, of a casing entirelyiuclosing said pulenoneu P. oa'euoan.
